Abstract
A mobile communication device is provided with a wireless module and a controller module. The wireless module performs wireless transceiving to and from a service network. The controller module receives, on a paging channel, a first predetermined number of symbols in a frame of a time slot via the wireless module, and determines whether to enter a standby mode according to the first predetermined number of symbols. Also, the controller module stops the receiving of subsequent symbols in the frame by deactivating the wireless module in response to entering the standby mode.
Claims15
A mobile communication device, comprising:
- a wireless device performing wireless transceiving to and from a service network;
- and
- a controller device receiving, on a paging channel, a first part of a plurality of symbols in a frame of a time slot via the wireless device, determining to enter a standby mode in response to the first part of the symbols being equal to the same amount of symbols which comprise only a fraction of a null General Paging Message (GPM), receiving subsequent symbols in the frame in response to the first part of the symbols not being equal to the same amount of symbols which comprise only the fraction of the null GPM, and stopping the receiving of subsequent symbols in the frame by deactivating the wireless device in response to entering the standby mode,
- wherein the first part of the symbols comprises only a fraction of the frame, and
- wherein the controller device further enters the standby mode in response to successfully generating the frame right after decoding the first part of the symbols, and receives a second part of the symbols subsequent to the first part of the symbols in the frame in response to not successfully generating the frame right after decoding the first part of the symbols, wherein decoding the second part of the symbols successfully generates the frame, and wherein the second part of the symbols comprises only another fraction of the frame.

A power saving method for paging operations in a mobile communication device, comprising:
- receiving, on a paging channel, a first part of a plurality of symbols in a frame of a time slot, wherein the first part of the symbols comprises only a fraction of the frame;
- determining to enter a standby mode in response to the first part of the symbols being equal to the same amount of symbols which comprise only a fraction of a null General Paging Message (GPM);
- receiving subsequent symbols in the frame in response to the first part of the symbols not being equal to the same amount of symbols which comprise only the fraction of the null GPM;
- stopping the receiving of subsequent symbols in the frame by deactivating a wireless transceiving function in the mobile communication device, in response to entering the standby mode;
- entering the standby mode, in response to successfully generating the frame right after decoding the first part of the symbols;
- and
- receiving a second part of the symbols subsequent to the first part of the symbols in the frame, in response to not successfully generating the frame right after decoding the first part of the symbols, wherein the second part of the symbols comprises only another fraction of the frame;
- wherein decoding the second part of the symbols successfully generates the frame.

A mobile communication system, comprising:
- a service network, operating in a slotted mode;
- and
- a mobile communication device receiving, from the service network, a first part of a plurality of symbols in a frame of a time slot on a paging channel, determining to enter a standby mode in response to the first part of the symbols being equal to the same amount of symbols which comprise only a fraction of a null General Paging Message (GPM), receiving subsequent symbols in the frame in response to the first part of the symbols not being equal to the same amount of symbols which comprise only the fraction of the null GPM, and stopping the receiving of subsequent symbols in the frame in response to entering the standby mode,
- wherein the first part of the symbols comprises only a fraction of the frame, and
- wherein the mobile communication device further enters the standby mode in response to successfully generating the frame right after decoding the first part of the symbols, and receives a second part of the symbols subsequent to the first part of the symbols in the frame in response to not successfully generating the frame right after decoding the first part of the symbols, wherein decoding the second part of the symbols successfully generates the frame, and wherein the second part of the symbols comprises only another fraction of the frame.
